KNOW ALL MEN BY THESE PRESEIVIS:l

That I, JOSEPH CHASE, of the city and county oi' Worcester, andCommonwealth 'of Massachusetts, have invented certain new and usefulImprovements in Machines for Making Clouded Yarn and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification, in which- Figure I represents a side view oi my improvedmachine, and

Figure 2 represents a longitudinal central section.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe it in detail.

In the drawings, A A represent the main frame of the machine; B the maindriving-shaft or cylinder, from which motion is communicated, by meansof bands C, to the spindles D, which are arranged in proper bea-'ringsat thc front of the frameA Only one spindle, whirl, ring, and travellerare shown in the drawings, as they are sufficient to illustrate myinvention, which relates to a diiierent part ofthe machine. In properbearings upon the top of the machine, and near the front thereof, arearranged the feed-rolls F F', and `just back of them another set offeed-rolls G G. Above thc feed-rolls, and about midway between the twosets of rolls, is arranged the thread-guide II, as indicated in thedrawings. I is a spool oi' wool roving or roping, and J a spool ofdouble woollen yarn ready to be twisted. Both ofv these spools turn inproper bearings. The feedrolls F F have a continuous motion imparted tothem by means of a belt, K, which runs from a pulley on the end of thecylindersliaft B to the pulley Ii, fast on the bottom roll F, while thefeed-rolls G G have an intermittent motion imparted to them by means ofthe pulley M acting upon the pulley N, fast upon the journal or" thelower feed-roll G. Pulley M has an enlargement, a, on a part of itsperiphery, which runs in line with the periphery of `pulley N, so thatat cach revolution of pulley M the part a will come in contact with theperiphery of pulley N, when, as the result of the friction of the twosurfaces, motion will be imparted to pulley N, and consequently to thefeed-rolls G G, so long,r as the enlarged or projecting part a remainsin contact with the periphery of pulley N. In this instance the pulley Nis covered with a rubber band, b, and the projecting part a is alsorubber, but any other desirable mode of giving an intermittent motion tothe feed-rolls G G may be employed.

The operation is as follows: Motion being imparted to the cylinder B inany well-known manner, the feedrolls F F are set in motion, when thethread or threads from the spool J will be drawn through guide H by thefeed-rolls F F', and delivered to the windingr and twisting device,which in this instance consists of the spindle D, whirl E, ring c, andthe traveller d, which are put in motion by the band G, as beforedescribed. The yarn is wound upon the bobbin O as fast as it isdelivered by feed-rolls F and F. The ring c is attached to rail I),which is to have a traverse motion imparted to it in the ordinarymanner. lhe twisting and winding device, above described, is well knownin the art of spinning cotton yarn, as ring spinning, and therefore doesnot require any further description. While, however, the thread orthreads e are passing forward, as above described, from spool andthrough `eed-rolls F and F', to the bobbin O, the rovingf is fedforwardat regular intervals by the feed-rolls G G, and being on n linewith the threads e it passes through feed-rolls F F', and is twisted inwith the threads e, giving to the thread, after it has been twisted, thcclouded appearance shown at g g, iig. 2 of the drawings. As soon as theFeed-rolls G G stop the rovingfisdrawn apart between the two sets offeedrolls, and the end ofthe roving remains extended, as represented atit, in close proximity to the threads e and rolls F F, so that it isalways sure to enter between the latter, with the former, whenever thefeed-rolls G G Feed it forward.` 'l'he roving may bc of any desiredcolor, and two or more different-colored strands of roving may be fed inat the same time to be combined together in the same thread I have shownone mode in which my invention may be carried out, but it is evidentthat the mechanism cnn be varied in a great many ways. Fluted feed-rollsmay be used, and'one or both sets may be driven by gearing, ifpreferred. 'lhe machine, too, maybe built so as to cloud any desirednumber of threads at the saine timeA l Having described my improvedmachine for elondin` yarn', what I claim therein new and oi' myinvention, and desire to secure by Letters Patent, is-

1. The combination, in a machine as described, with `the yarn-feed rollsof the roving-feed rolls, or their equivalents, in such manner thatwhile the yarn or main thread is fecl forward, with a continuous motion,the feed of the roving, to the said thread shall be intermittent, as andfor the purposes specified.

I 2. .The combination of the yarn-feed rolls with the rolls forproducing the intermittent feed of the roving, arranged and mounted inthe machine relatively to the said yarn-feed rolls, as and for thepurposes herein described. i

3. The combination, with the feed-rolls G G and F F7 of tho yarn-guideH, whereby the.yarn is fed down upon the back of the roll F, while theend of the roving is left in close proximity tothe latter, as shown anddescribed.

4. The combination, with a machine for winding and twisting threads ofyarn, of an intermittent roving feeding mechanism for clouding the yarn,substantially as set forth.

JOSEPH CHASE.
